This Performance Air Intake System allows your engine to breathe more air compared to the restrictive factory air intake housing. It is designed, tuned and dyno-tested to produce more horsepower and torque. Air enters the system through an oversized AEM Dryflow synthetic washable air filter for outstanding air flow, filtration and performance. The air intake tube is constructed from mandrel-bent aluminum featuring a durable silver powder coated finish. A custom shaped heat shield with lid is included. The tapered cylinder shaped AEM Dryflow air filter is made from an oil-free, synthetic filter media that can be used for up to 100,000 miles before cleaning is needed (depending on driving conditions). This Air Intake System is backed by AEM's Lifetime Limited Warranty.
